2019 F350 SRW 6.7 with 19,000 miles. The A/C stops blowing cold. Took to dealership and they advised 2 O-rings had blown out causing all the refrigerant to leak out. Dealership repaired under warranty. Now 3 weeks later @ 20000 miles the A/C is not blowing cold again. Taking is back for a second time to have the issue addressed. It appears there may be a common issues with this truck, as several others are experiencing the same thing.
It has been in the shop 3 times. They replaced the control unit. Replaced a valve on the coils, and they say the pressure is too high. It is in the shop again.
Update from Jan 28, 2021: After replacing almost ever part except the whole system. The found a inline switch that was failing and falling apart into the link blocking the high pressure .
